Army school in Mumbai is a very good school as of I heard. It is a CBSE(Central Board of Secondary Education) Board. It is opposite INHS Ashwini Hospital.
It is run by Indian Army and under it supervision. It is a part of Army Public School network.
My niece was in this school. The class rooms of the school are big and spacious. There is a student activity centre where students perform various co-curricular activities. They have nice laboratories.
The teachers are also very good and helpful.
Discipline is the major key of this school. So I recommend you guys to send your children in this school.
It is really a good school.
